Wow Jim, just wow.

You'e poured your heart and probably the 180 trillion quid Gordon Brown knows into that. Looks great.

Did you buy it not knowing what state the engine was in?

cheers

i knew about the cooler, exhaust, turbo, powerFC and possibly some cams, but that was it.
i took a chance on it really, i had no plans to sell my rev2 at all, but it just popped up for sale, and id remembered seeing a thread from rash at ramotors a while back saying theyd imported a rev5. saw pics and was well jealous. months later it was for sale again!
literally saw it for sale on a friday, drove up to midlands on the sunday and bought it!! big decision really as my rev2 was awsome! got 4.1k for my rev2 tho, kept a few mods and sold a few things on to help pay for the rev5.
it was a big gamble tho!

all the mods you see ive pretty much discovered over the time ive owned it, most if not all are phoenix power related.
ive obviously put my own mark on it engine wise, with the detailing, custom manifold, bov, WI, slight interier and ice upgrades, but the exterier remains the same. subtle i think.
i just want to maintain what the car once was i guess. a jap street monster i would have thought! i did see recorded readings of 2bar on my apexi EL1 boost gauge when i got it!!!! 2bar!!! :shock:, obviously ran that back in japan.
the engine has every sign its been tuned by phoenix power as well, this has been the biggest bonus!

however finding out it has been running a tooth out on the cambelt all this time, 1year+ has been the biggest eye opener really! the car used to sound like a full on race car on idle, i put it down to mental cams, but it was obviously due to the cam being a tooth out, coupled with the agressive cam setup. sounded amazing tho i have to say, lol! since sorting it out its better low revs to drive, idles lower and is certainly less loud and lopey at idle, and with any luck, should release more power with the cam corrected.

also had a the fuel pump go weak on me, was an old GTR pump in there, took me 4months of diagnosing to find that out!! 4months off the road playing with it every weekend to try and find out what was up with the car (all in a separate thread somewhere)! nightmare!
glad i could sort that out on the drive and it wasnt anything serious.

interesting experience i have to say discovering all these goodies and being a rev5 as well. i wont be selling anytime soon!

remap time very soon!
hoping for 360-400hp

With that spec I'd have thought you'd be looking at the latter half of the 400's easily!

It's a beautiful looking car and you're dead right about leaving the exterior as near to standard as possible.

Was it an effort getting the 255/18's under the rear arches? Thats a hell of a lot of extra wheel. My 225/18's were close :shock:

I'd love a nice Rev 5 tubby. It's possibly the only way I'd get another one tbh.

the arches are rolled....
is very tight on the 9j wheel...et42 tho!
wheels came with the car, same bbs lms phoenix power like using on there cars.

restrictions matt are the sidemount ic, the fact i still have a cat in there (be it a high flow phoenix power one) plus the turbo is only rated to 520hp, and id imagine that 520 is on something like a 2.5ltr skyline. so not sure what itll do on a 2ltr car. plus thats at 2.4bar, ill be running much less than that. id think mainly sidemount ic is my biggest problem to get high hp out of it.

really not sure on the power, it made 342hp at 1.15bar, but with a cracked to hell manifold, no cooling fans, wastegate valve loose, cam out a tooth.
id really be happy with late 300s...
if i could crack 400hp id be over the moon and leave it there.

the thing is insane compared to my old car, lol. i like the fact it scares me, lol.
hopefully mapping for 1.5+bar

You'll find it horrible to drive it you aim for headline power anyway Jim. I've never seen a really high power 2.0 4 cylinder car that has a power graph that looks pleasent. They all look like a cliff. Flat, flat, flat, flat 6k revs and verticle.

:lol: You need to look further!

Jim seeing as your cars a 1998, if its got the original block still, it should have the extra meat around the water pump. Is it running 86mm pistons aswell?

If so you should be able to push 2+bar if you can keep the intake temps/egts in check without the worry of the block cracking as much :thumleft:

Get a bootmount on it and get it down the strip!

Could sell your I/C and install a bootmount for probably less money!

Are you getting it mapped using the meth?

Are you still running standard internals?

Have you investigated?

Find me a 500+ bhp MR2 retaining a 2.0 capacity that's making good boost and power (IE 85%) before 5.5k rpms.

I'm not denying you can make the power, you can make a whole lot more. But making it pleasant and useable is a whole other matter.

How about 700+hp and 580hp and 540 lb/ft torque @5500rpm.


Image

That was the first graph I came to.

Have you actually driven a high power MR2 to see how they actually spool?

The cars will always spool better on the road aswell.

If your only wanting 500hp you can probably bring that spool down to 3.5k ish on a smaller GT30 sized turbo?

Maybe with the old T88 etc turbos they were nothing nothing then take off, but the newer technology about and advances in tuning mean its not at all bad.

Heres a video of my car after its very first tune @ only 1.2bar IIRC, making about 460+.

Even though the tune wasnt optimised by a long way, there was plenty of useable power low down, mid and top!

Its better now and will be alot better after the next tune.

Lol, that graph is proving my point!

4.5k rpms it's barely making standard power!

I cant wait to see Jonny's graph and see the difference big CC makes to the big turbo and the power delivery.

But is it? When does a standard rev3 make max power, 6.5k? 220hp?

That graph above makes that @ 4.3k? but then go's on to make 720hp :lol:

Theres a graph somewhere that shows a gt3071 IIRC with a ct20 plot overlayed, they both are together matching spool/power/torque until circa 3.2k and then the gt30 takes off to upwards of 450+hp?

I've been in 2 mild power MR2's, with standard turbo's on that were less pleasent than standard cars.

Have you been in a car that doesnt rely on huge boost and turbo's to make decent power?

You seem to have missed my point on the power delivery. Yes, that one is making standard power at 4,500rpms where as a standard car would be making it at 6.5k rpms. But the standard car would be making more of a percentage of it's maximum power by 4.6k rpms.

Mine was about 300bhp, it was making more than that one was at 4.5k rpms I can tell you.
