Europeen style 3800 turbo swap - what do you think ? (Page 5/14)
Englishrafe MAR 12, 05:08 AM
For those who think that I should keep the static ratio lower.
The results using "8.5:1" - 8.28:1 (real) pistons:
10psi boost = 10.17:1
12psi boost = 10.91:1
15psi boost = 12.03:1
20psi boost = 13.88:1

Yeah I know this is more reasonable, but what's the "driveability" of this set up ?
I don't want to hang arround waiting for spool-up -- my Renault 5 Gordini Turbo was horrid to drive anywhere else but on the track!

Edit: Yes, I own my second page !!!!

Ooooh interesting build Raife. Have no idea how you managed to hear about a 3800 and so far away and such low miles! Jealousy is not a good trait.

Thanks for sharing.

Cheers

With that tinny tiny little turbo on there you should have no problems spooling it quickly... The turbos we have on most all of our stuff over here is roughly 1.75x bigger than that gt37.

The big T3 exhaust you have wont help your setup much at all, other than give you a bit more room passed 5500rpms (which you wont be able to go much higher than 6000rpms anyway). It will cost you more spool than it helps you in horsepower...

Most 3800s with that sized turbo will be limited to less than 500 bhp on 93 octane (I think they measure it 98 in EU), and at most 600 on better fuel.

Ebay.de (German Ebay) - Had been looking all over Europe for one!
Not so sure about the miles any longer - the exhaust valves were a bit pitted on their seats. However, the crank and the block bores were spotless, so that's what counts!

And I thought it was a fairly big one !? Well I guess everything is relative....
Thanks for the advice - 400/500HP is right where I want it for everyday use.
I can always buy some 110 race fuel the next time I go back to England and to Santa Pod - be fun to push it to 600 on a run!

I am going to order my con rods soon.
Could someone please confirm the length of "L32" type con rods ? (Length center to center)
There seems to be some difference in length between the N/A rods and the SC rods - and since I will be using forged SC type pistons, I need to get it right !
(I have only a set of N/A rods as reference.)

I'm going for H-beam type rods and the seller wants me to make sure that I have ordered the correct length - his rods are pretty much made to measure.

Thanks

Nice build. I'll follow this one. I was looking for a long time for a S2 3800 on ebay.de but the prices were always too high for my liking.

Yes, most of the time the 3800 (ex 3.8 Camaro) listed are about 1000+€.
I was lucky to come across my engine!


Anybody for the con rod lengths ? (Probably too early in the USA - still night time !)

and forgive me it's an mr2 photo



That does look sweet and i like mr2s just not as much as fieros.

Here's an update.
I have been busy on other things like repairing my house and driving my Trans Am arround western France to go to all the different meetings!






But I finally got a bit of time to put the valves back in the heads:






Still have not ordered the pistons - maybe next month...!
